Roth is Myer Lansky who was a financial and strategic advisor to the mob. He did not command troops. He had no family. Moe Green is Bugsey Siegal who was a Murder Inc. hood who found his niche in Las Vegas. He had ties to the Mafia and Jewish hoods, but he did not have a family either.
I just posted on Murder Inc. and Siegel's brush with them in the Mob Myths vs. Reality thread:
